Adrian Sutil has added yet another dissenting voice to F1 drivers' collective dissatisfaction with Pirelli's 2013 tyres.
"It is not really fun to drive on these tyres," the Force India driver, who returned to the grid this year after a sabbatical, is quoted by Auto Motor und Sport in Japan.
Sutil joins Fernando Alonso, Mark Webber and Sergio Perez in criticising Pirelli's tyres in recent days and weeks.
"You have to say that, actually, these are not like formula one tyres," he added.
Sutil said: "I hope we can find a better situation in the future."
